Hi,
Lately, I have been facing this issue in the emacs built from master branch. I haven't yet seen this error occur on emacs 24.4.
I see it happen now and then and haven't been able to consistently reproduce it but here is the backtrace. I have not been able to create this error on "emacs -Q".
I get this error when I am trying to quit isearch. I don't know if this happens when I try to quit after I tried to search for a term that failed to be found in the buffer or when I try to quit after a successful search hit.
But once this started happening, repeated C-g hits keep on throwing this error and I can't quit isearch.
Then the only way is to restart emacs.
